AI Article Synopsis
- The healing of traumatic ulcers depends on growth factors to rebuild tissue after inflammation, and liquid rice hull smoke (LR-HS) has anti-inflammatory properties that may assist in this process.
- In an experiment, Wistar rats with induced traumatic ulcers were treated with LR-HS for different durations, and their tissue was analyzed for growth factors like FGF, VEGF, PDGF, and COL-1 after treatment compared to a control group.
- Results showed that LR-HS significantly increased the expression of all the growth factors studied, suggesting its potential as a herbal medicine for promoting healing in oral ulcers.
Article Abstract
Objective: The healing process of a traumatic ulcer requires growth factors to rebuild the lost tissue after the inflammatory process has been completed. Liquid rice hull smoke (LR-HS) has shown unique anti-inflammatory properties. This study analyses the role of LR-HS in growth factor stimulation for the healing of traumatic ulcers, such as fibroblast growth factor (FGF), vascular endothelial growth factor (VEGF), platelet-derived growth factor (PDGF), and collagen type 1 (COL-1) expression.
Methods: We obtained LR-HS from the pyrolysis of rice hulls. Traumatic ulcers were created in the labial fornix incisive inferior of Wistar rats and treated with LR-HS once a day for 3, 5, and 7 days. The control group was treated with sterile water. Each animal was sacrificed after treatment, and its labial fornix incisive inferior tissues were biopsied and immunohistochemically stained to examine FGF, VEGF, PDGF, and COL-1 expression.
Result: The treatment of traumatic ulcers with LR-HS showed an increase in FGF, VEGF, PDGF, and COL-1 expression. VEGF expression increased under LR-HS treatment compared with the control 7-day treatment groups ( < 0.000). FGF and COL-1 expression increased under LR-HS treatment compared with the control 5- and 7-day treatment groups ( < 0.000). PDGF expression increased after treatment with LR-HS for 3, 5, and 7 days ( < 0.000).
Conclusion: This study has demonstrated that LR-HS can induce the expression of growth factors during the healing of a traumatic ulcer using immunohistochemical staining. We suggest that LR-HS can be used as a herbal medicine for oral ulcer therapy.

Objectives: To characterize the serum cytokine profile in myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD) at onset and during follow-up and assess their utility for predicting relapses and disability.
Methods: This retrospective multicentric cohort study included patients aged 16 years and older meeting MOGAD 2023 criteria, with serum samples collected at baseline (≤3 months from disease onset) and follow-up (≥6 months from the baseline), and age-matched and time to sampling-matched patients with multiple sclerosis (MS). Eleven cytokines were assessed using the ELLA system.

Purpose: Immune checkpoint inhibitors (ICIs) have demonstrated promise in the treatment of various cancers. Single-drug ICI therapy (immuno-oncology [IO] monotherapy) that targets PD-L1 is the standard of care in patients with advanced non-small cell lung cancer (NSCLC) with PD-L1 expression ≥50%. We sought to find out if a machine learning (ML) algorithm can perform better as a predictive biomarker than PD-L1 alone.

Mechanistic understanding of the inhibitory immunoreceptor PD-1 is largely based on mouse models, but human and mouse PD-1 share only 59.6% amino acid identity. Here, we found that human PD-1 is more inhibitory than mouse PD-1, owing to stronger interactions with the ligands PD-L1 and PD-L2 and more efficient recruitment of the effector phosphatase Shp2.

The detection of Estrogen Receptor (ER), Progesterone Receptor (PR), and Human epidermal growth factor receptor 2 (HER-2) is important for the stratification of breast cancer and the selection of therapeutic modalities. This study aimed to determine the quantitative expression of ER, PR and HER-2 using Immunohistochemistry and their correlation with quantitative baseline Ct values measured using Quantitative Polymerase Chain Reaction (PCR). This study also assessed the use of fresh breast tissue biopsies preserved in RNAlater solution in the quantitative detection of these receptors using PCR technique.
